Two questions I asked myself when we were faced with a similar dilemma:
Are you secure enough in emergency savings, after paying the larger downpayment?
Will the invested difference earn more than the interest rate on the car loan?
That is a great question, and it looks like we have some great advice from our members. If you do have any additonal questions, you can also contact one of our financial advisors at: 1-800-771-9960. This is a service that may be used for free with you membership.
